STYLE GUIDE

we have need

for

  • You’ll have an easy guide to refer to when handing over the project.
  • You maintain control of the design. When someone does something awful, you can refer them to the document.
  • You avoid cheapening the design, message and branding.
  • Makes you look professional. They’ll know you did everything for a reason

RWD

Build smaller, tactical teams that are capable of executing multiple rounds of planning, design, and code quickly and independently."

 

— Trent Walton

Responsive Workflow 

Instead of dividing teams into skill sets,

build complementary teams , focused on small tasks.

Each small team tasks:

  1. A project starts with building “ all-round”-teams;
  2. Think mobile first = commitment to the content,
  3. Produce style tiles, first modules in Photoshop,
  4. Build prototypes in the browser ASAP,
  5. Atoms first; modules, organisms later,
  6. Collaboration as “in-browser design pairing”.
  7. Clients sign off new deliverable:
  • Style guides and prototypes,
  • Core content/functionality priority lists,
  • Performance and UX budgets,
  • Legacy browser support,
  • Responsive images strategy.

SKETCHES

RESPONSIVE WEB DESIGN is

  • A Flexible Grid (Fluid: % + Min Widths)

  • Flexible Media (Images, Video)

    • ​img { max­‐width: 100% }

    • FitVids.js

  • (Not Just) Media Queries

    • @media (min­‐width: 20em) { /* CSS goes here */ }

RWD 

Media Query

!==

The way in which CSS media
queries
have been promoted for
mobile hides tough problems and
gives developers a false promise
of a simple solution
for designing
for small screens .

images downloading

Recommendations

  • For hide a content image, display:none isn't working.
    • Using a Javascript or server-side based approach instead
  • For hide a background image, hide the parent element.
    • If you can’t do that, then use a cascade override (like test four)

make them responsive

Don’t just optimize images

Allows authors to define various image resources and "hints" that assist a user agent to determine the most appropriate image source to display (e.g. high-resolution displays, small monitors, etc).

Srcset attribute - CR

A responsive images method to control which image resource a user agent presents to a user, based on resolution, media query and/or support for a particular image format

Picture element - CR

CSS Font Loading

This CSS module defines a scripting interface to font faces in CSS, allowing font faces to be easily created and loaded from script. It also provides methods to track the loading status of an individual font, or of all the fonts on an entire page.

CSS Font Loading - CR

<script>

  document.fonts.ready().then(function() {

    document.documentElement.setAttribute( "class", "fonts-ready" );

  });

</script>

<style>
    p {
        font-family: sans-serif;
    }
    .fonts-ready p {
        font-family: iran-sans;
    }
</style>

Enabling Font Loading 

fontfaceobserver

polyfill

<!--#if expr="$HTTP_COOKIE=/fonts\-loaded\=true/" -->
<html lang="fa" dir="rtl" class="fonts-loaded">
<!--#else -->
<html lang="fa" dir="rtl">
<!--#endif -->

<head>
    <style>
    body { font-family: sans-serif; }
    
    .fonts-loaded body { font-family: "iran-sans-light", sans-serif; }
    </style>
    
    <script>
      (function( w ){

        if( w.document.documentElement.className.indexOf( "fonts-loaded" ) > -1 ) return
    
        new w.FontFaceObserver( "iran-sans-light" )
          .check('ایران')
          .then( function(){
              w.document.documentElement.className += " fonts-loaded"
          });

      }( this ));
    </script>
</head>

Enabling fonts once loaded

javascript

javascript can block

With scripts, progressive rendering is
blocked for all content below the script.

javascript that Doesn’t block

<script	src></script>	

</body>

javascript that Doesn’t block

<head>

  <!--  Downloads right away  -->
  <script src async></script>

  <!--  Waits to  download  -->
  <script src defer></script>

javascript that Doesn’t block

var script     = document.createElement("script");

script.type    = "text/javascript";

script.src     = "foo.js";

script.async   = "";

var ref        = document.getElementsByTagName('script')[0];

ref.parentNode.insertBefore(script, ref);

CSS

stylesheets block

  • Browsers (except Opera) block rendering until all screen CSS arrives. With the worst possible experience: white page.
  • Browsers download CSS they don't need, e.g. print, tv, device-ratio... And most browsers (except Opera and Webkit)

CSS downloading

Solutions

  • CSS is sacred. Choose minimal when possible.
  • Separate <link> elements for each breakpoint
    • Doesn’t scale.
    • Good for WebKit, what about everything else
  • Separate out and inline your Critical CSS.
